It does not...

Of course, in order to index an object under a value,
the object must have a attribute (or method) the returns
this value.

ZClasses come with "PropertySheets" (to define attributes)
and methods. Both can be used for indexing (and MetaData determination).

Without ZClasses, your options are:

  *  properties

  *  acquired methods (usually PythonScripts)

  *  persistent classes in products with their attributes
     and methods

  *  Archetypes.

Reread the "Searching" section in the Zope Book.
